so i think it would be more efficient for the commission to simply take a live evidence. there may be some witnesses where the two sides can agree on on fairly uncontroversial measures, and to the extent we can do that, we will make every effort to do that. we do not want people to have to come in and give testimony in an uncontested manner. but for the witnesses i mentioned earlier, the independent witnesses, i think there is no question that they will be subject to extensive cross-examination, and that will require redirect on our part, fill in the blanks, so i think ultimately, we all save ourselves and the witnesses are lot of trouble, because, remember, these witnesses do not work for the city. they did not ask to be called as witnesses. they did not ask to try to declarations. to the extent they are cooperating with us, they are cooperating out of a sense of civic duty, and i think we should try to make its board and on them not so heavy.
